Synopsis An upper level ridge will bring sunny and warmer weather
to western washington through Tuesday, except for some isolated
morning low clouds. An upper level trough will approach the region
Tuesday night producing onshore flow and allowing more clouds and
cooler weather to return Wednesday and Thursday. Another upper level
ridge will build over the area next weekend.

Short term Visible satellite imagery shows clear skies over W wa
this morning, except for a little bit of stratus and or fog on the
central coast near grays harbor. Water vapor imagery shows the
approaching low amplitude upper level shortwave ridge out near 135w-
140w this morning. Models remain on track with the approaching
ridge. Northerly low level offshore flow has developed over W wa and
will continue through Tuesday as the ridge traverses the region.

Temperatures will be a little warmer today with highs in the 70s to
lower 80s. Warming from the ridge and weak low level offshore flow
on Tuesday should push highs up into the lower to mid 80s in the
warmest spots.

The ridge axis should be over the coast Tuesday afternoon then shift
over the id panhandle by 12z 5 am Wednesday morning. A weak upper
level trough will be right behind the ridge. This eastward
transition of the ridge and trailing trough are good indicators of a
marine push. Onshore flow will increase Tuesday evening, but the
weak to moderate pressure gradients indicated by the models suggest
only a shallow marine layer will reach puget sound Wednesday morning
before dissipating before midday. This may yield about 5 degrees of
cooling on Wednesday. Kam

Long term On Thursday, the SE part of a large upper level trough
will have settled over W wa with SW flow aloft. More important is
that a surface ridge just offshore will maintain a moderate onshore
flow pattern. A couple more nights of onshore flow Wednesday night
and Thursday night should produce a gradually deeper marine layer
over the interior. Skies should clear by afternoon once again on
Thursday, but the low clouds might last a little longer and cover a
bit more of the lowlands on Friday.

The models remain in flux for this weekend. Run-to-run consistency
has not been very good. The GFS had been advertising the SW u.S.

Ridge building northward over the area but has now migrated to the
ecmwf solution. The consensus now is that the large upper level
trough offshore will eject NE across b.C. This weekend, in the
process keeping W wa under SW flow aloft, onshore flow, and a cooler
air mass. This should keep temperatures pretty close to normal. The
models now postpone the strengthening SW u.S. Ridge until next
Monday. Kam

Aviation A broad upper ridge will be over the area today and
tonight with northwest flow aloft. At the surface, onshore flow
will continue with high pressure offshore and lower pressure
inland. The air mass is dry and stable. Patchy valley low clouds and
fog should burn off later this morning.

Ksea... Clear. Northerly winds 5-10 knots, strongest this
afternoon and early evening. Schneider

Marine Varying degrees of onshore flow will continue through
Friday with high pressure offshore and lower pressure inland.

Small craft advisory strength northwest winds will continue over
the outer coastal waters through Tuesday. There will also be small
craft advisory northwest winds for the inner coastal waters the
next couple of evenings.

The central and eastern strait of juan de fuca should have small
craft advisory west winds each evening for the next several days.

Gales are possible each evening starting Tuesday. For now, the
best chance of gale force winds looks like Wednesday evening.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
